4 claims. (ci. ce1-92) This invention relates to an airconditioning device, the general object of the invention being toprovide a device of this nature which can be manufactured to sell at low cost, and which will operate with minimum expense and one which will effectively clean the air and which can be used in cooling or heating the air as desired.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts toibe hereinafter fully described, illustrated in the accompanying drawings and speciically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in whichr- Figure 1 is a side elevation of the device,

Figure 2 is a view looking towards the motor carrying and of the device,

Figure 3 is a view looking toward the outlet end of the device,

Figure 4 is a vertical longitudinal sectional view` through the device,

Figure 5 is a transverse sectional view through one of the vanes before the same is curved or bent,

Figure 6 is a longitudinal sectional view through said vanes,

Figure 7 is a fragmentary sectional view showing how a trough is slidably arranged in the cylinder.

In these views, the numeral I indicates a-cylinder which is supported in horizontal position by the base member 2. Both ends of the cylinder are open, although the inlet end has a plate 3 extending across the lower part and aA spider-like cap 4 fits over said end and has its central part supl porting the motor M which drives the fan 5. A

trough 6 rests in the bottom of the cylinder and the plate 3 acts -as a stop for limiting movement in one direction of the trough, the trough being slidably arranged in the cylinder vand has its edges engaged by theD guidel ways 1. Uprights 8 are attached to the ends gf the trough and have their upper ends forming bearings for a shaft 9 of the rotor which includes the vanes 9 suitably connected 4with the shaft and each vane includes a sheet l ofl absorbent material anda cover II of wire mesh or the like which covers the absorbent material. The covering material extends well beyond the outer edge of the absorbent matep rial, as shown in Figure 5, and it also extends to a limited extent beyond the ends of the absorbent material and each vane is curved as shownmore` particularly in Figures 2 and 3 so that air from the fan striking these vanes will rotate the rotor.

' vanes at the outlet end of the device while a plain strip I is connected to the front end of the vanes as shown in Figure 2. Water or other liquid is placed in the trough and the level of this 1'0- water or liquid can be slightly below the outer edge of the absorbent material I0 of each vane, so that said absorbent material will not enter the water but the water will be carried upwardly by the projecting part of the cover II and will then pass downwardly upo'n the absorbent material, thus preventing the absorbent material from being water-clogged and becoming so heavy as to interfere with the proper rotation of the rotor under the action of the air from the fan which iS controlled by the spiral ribs I3 which directs the air from the fan against the outer edges of the vanes and between the vanes with such force that a continuous pressure against the vanes is developed, so that the cooling eciency ofthe device is increased. As the rotor revolves the projecting part oi the covering IIv will pick up the cooling liquids in the tray and spread or diiIuse the same through the absorbent material' thereby providing a highly eiilcient cooling circuit and in turn resulting in prop er air conditioning.

As will be understood, the tray and the rotor can be pulled entirely from `the cylinder for rrepair or' inspection purposes and can be partly ing the tray more or less into the cylinder the cooling action can be controlled for by moving the tray outwardly the current of air passing through the cylinder may be more quickly diffused, 4o thereby quickly cooling the room or space to be cooled. 4 i V The strip or band Il around the discharge end of the rotor serves the purpose of .catching the water or liquid which drips and .preventing it from being thrown outsidey of the unit by leading the excess'downwardly through said strip'l back into the tray.

While the drawings show thevanesas of spiral shape in some instances they may be made straight and the spiral ribs relied upon to so direct the air against the vanes that said air will rotate the rotor. i

It is thought from the foregoing `dcription that the advantages and novel features oi the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having thus described my invention what is claimed as new is:

1.' An air conditioning device of the class described comprising a cylinder, a rotor mounted in the cylinder and including vanes and each vane composed of absorbent' material and a mesh covering which extends outwardly beyond the absorbent material, a liquid containing trough in the cylinder through which the vanes pass with the liquid level below the outer edge of the absorbent material, means for forcing air into one end of the cylinder and spiral ribs on the internal wall of the cylinder for causing the air to engage the vanes to rotate the rotor.

2. An air conditioning device' of the class described comprising a horizontally arranged cylinder, a trough slidably arranged in the lower part of the cylinder, uprights at the ends of the trough, a rotor shaft supported by said uprights, vanes carried by the shaft and each vane including an absorbent sheet and mesh covering which extends beyond the outer edge of the sheet, said trough adapted to contain liquid, the level of which is below the sheet and means for forcing air into one end of the cylinder to rotate the vanes and shaft.

3. An air conditioning device of the class described comprising a horizontally arranged cylinder, a trough slidably arranged in the lower part of the cylinder, uprights at the ends of the trough, a rotor shaft supported by said uprights, vanes carried by the shaft and each vane including an absorbent sheet and mesh covering which extends beyond the outer edge of the sheet, said trough adapted to contain liquid, the level of which is below the sheet and means for forcing air into one end of the cylinder to rotate the vanes and shaft, and said means including a motor driven fan supported from said end of the cylinder.

4. A device of the class described comprising a horizontal cylinder, a trough in the lower part thereof slidably arranged therein, uprights carried by the trough, a shaft carried by the uprights, vanes carried by the shaft and each vane including a sheet of absorbent material and a` wire mesh covering which projects beyond the outer edge of the sheet and said trough containing liquid, the level of which is below the outer edge of the sheet, a strip of mesh extending around the outer corner of the vanes at the outlet end of the device, and means for forcing airinto the inlet end oi' the device.
